That's odd, and tracking it down would probably be interesting, but why
do you care?  A _TCP_ packet, no matter what it contains, should not
affect a _UDP_ BOOTP client.

If the machine is quiet enough that it's not insane, you should be able
to catch any userland source with "ktrace -i -d -p 1", provoke the
symptom, "ktrace -C", in as quick succession as you can.
